    4000-year-old hair from the Middle Nile

    4000-year-old hair from the Middle Nile highlights unusual ancient DNA degradation pattern and a potential source of early eastern Africa pastoralists

    Abstract
    Petrous bones and teeth are the skeletal elements most often targeted by researchers for ancient DNA (aDNA) extraction, and the sources of the majority of previously published ancient African genomes. However, the high temperature environments that characterise much of Africa often lead to poor preservation of skeletal remains. Here, we successfully reconstruct and analyse genome-wide data from the naturally mummified hair of a 4000-year-old individual from Sudan in northeastern Africa, after failed attempts at DNA extraction from teeth, petrous, and cranium of this and other individuals from the Kadruka cemeteries. We find that hair DNA extracted with an established single-stranded library protocol is unusually enriched in ultra-short DNA molecules and exhibits substantial interior molecular damage. The aDNA was nonetheless amenable to genetic analyses, which revealed that the genome is genetically indistinguishable from that of early Neolithic eastern African pastoralists located 2500 kms away. Our findings are consistent with established models for the southward dispersal of Middle Nile Valley pastoral populations to the Rift Valley of eastern Africa, and provide a possible genetic source population for this dispersal. Our study highlights the value of mummified hair as an alternate source of aDNA from regions with poor bone preservation.

    Kadruka_4000ybp plots near the Kenyan Early Pastoralists who are close to the 4000 ybp age.I wonder if Kadruka also has heavy Mota ancestry like those Early Pastoralists or is it’s non-MENA ancestry primarily South Sudanese-like

    It's hard to really tell but that slight pull away from MOTA leads me to believe that this sample was more similar to the Kulubnarti Christian Era Nubian samples.

    Mota-like ancestry that we see in the Early Pastoralists might have been brought with them into the Horn and beyond.This might also explain the Omotic-like signal (6.8% according to Shriner's paper) in Natufians.Perhaps Mota-like groups had a far wider range in NE Africa

    "This in turn would point to a high degree of mobility of pastoralists between the Middle Nile Valley and present-day Kenya, potentially before or around the Pastoral Neolithic. It would imply that the southward dispersal of pastoralists from the Middle Nile Valley did not involve genetic exchange with pre-existing human groups along the migration route, particularly local foragers, and may therefore have been relatively rapid."

    Indeed, archaeological research suggests that dispersals were likely driven in part by increasing population pressure and regional aridification, with a marked period of aridity in Upper Nubia preceding the first appearance of pastoral groups in the Turkana Basin of eastern Africa at 5000 BP29,30,31. These early eastern African pastoralists at sites like Lothagam in the Turkana Basin29,32, while featuring regional forms of cultural expression, also broadly maintained traditions of monumental mortuary expression, as well as traditions of burial with elaborate grave goods for which the Neolithic and Kerma period cemeteries of the Middle Nile Valley, including Kadruka 1, are recognised9.

    Too bad they were not successful with the early Neolithic Kadruka samples, which might be related to (pre?) proto-Cushitic. But this is still great to see. A Kerma period sample closely related to early East African Pastoral Neolithic samples!

    Interesting how years ago it was suspected Cushites came from North Sudan due to simple analyses on E-M78 and now this study pretty much seals this hypothesis. The name Cushitic funnily enough was geographically correct despite the chronological misplacement.

    What I sometimes say the legends are often truer than many give them credit for. In any case no y-dna was recovered so we still don't know what line they had. E1b1b probably entered Sudan during the neolithic and Sudan probably had A in the paleolithic.

    Maybe deep into Sudan (South Sudan) had no E-M35 before the Neolithic, but we can't safely say that for North Sudan. It's too close to Egypt for that.
